The various steps of the developed algorithm were illustrated via a step-by-step detailed explanation of the important portions of the code which are involved in the mesh refinement procedure, providing The first change necessary to adjoin this code is to import the dolfin-adjoint module after loading FEniCS: from fenics import * from fenics_adjoint import * The reason why it is necessary to do it afterwards is because dolfin-adjoint overloads many of the dolfin API functions to understand what the forward code is doing. Topic Replies Views Activity; In FEniCS, these kind of problems are handled by defining subdomains inside the domain. g. Automatically generated API documentation is I am trying to build a Finite Element Analysis simulation in python using Fenics, all of which I am fairly new to. Dear all, I am struggling with a bug in my code that buffles me. mshr is an optional FEniCS library that provides meshing utilities.
